Scopulariopsis

Most members of the genus Scopulariopsis are soil fungi, which are frequently isolated from food, paper and other materials. They also occur as laboratory contaminants. Several species have been reported as causative agents of onychomycosis and hyalohyphomycosis (Sandoval-Denis et al. 2013). The most common species seen in the clinical laboratory is S. brevicaulis, followed by S. gracilis S. brumptii, Microascus cinereus, S. candida complex, and M. cirrosus (Sandoval-Denis et al. 2013).

RG-2 for species isolated from humans.

Morphological Description:Colonies are fast growing, varying in colour from white, cream, grey, buff to brown and black, but are predominantly light brown. Microscopic morphology shows chains of single-celled conidia produced in basipetal succession from a specialised conidiogenous cell called an annellide. Once again, the term basocatenate can be used to describe such chains of conidia where the youngest conidium is at the basal end of the chain. InScopulariopsis, annellides may be solitary, in groups, or organised into a distinct penicillus. Conidia are globose to pyriform, usually truncate, with a rounded distal portion, smooth to rough, and hyaline to brown in colour.
